One of the suggested methods is a halfway solution which allows developers to choose between third party currency or Facebook currency. This also has long term benefits for companies using Facebook fan pages to promote and potentially sell their products online.But this halfway solution of mixed credit payment solutions means that the switch to a pure Facebook currency may experience delays and may never reach true scale required to compete with Paypal or Google Checkout to be a true alternative.
While I can see the complex situation that Facebook have with their developers, it is unlikely that the developers would walk away from Facebook as its a successful platform. But the move towards a formal payment platform does require formal relationships between developers and Facebook which should help build formal development partnerships.
